3d printers under 300 Buyer’s Guide

In this article we will tell you different points to consider when buying the 3D printer’s all the tips are given below

How to choose the best 3D printer?

Although its first objective is not precisely to be a home appliance, we cannot ignore an increasingly closer reality in which these printers will be part of our daily lives. And domestic ones will be much more common than they can be today. So how to choose one that suits your needs?

Printing material, filaments, and reels:

These printers need a coil or filament reel. That can be either ABS, which is the acronym acrylonitrile butadiene styrene or polylactic acid.

These plastic materials are thermoplastic. They can become flexible upon contact with heat, but, when cooled, they return to their solid-state. Regardless of the times when this process is done, the effect will be the same.

Between these two, ABS is usually the favorite of professionals because of its high-temperature resistance. For its part, the PLA does not have the same capacity, but it is available in a wide variety of colors, so it is good for amateurs and lovers of environmental care because, being corn-based, it is a biodegradable material. Although that does not mean that is why it is less durable than ABS.

However, there are other materials. The important thing is to know what your machine supports. The diameters or the size of the reel that it is capable of supporting. So you have perfect printing material. Therefore some printers only support materials from the same manufacturer.

  • Nylon: The most popular of the nylon materials used for this purpose is in 618 nylon, which is used mainly in the medical industry, in jobs such as the creation of external implants. Its natural white color is ideal for coloring it the color you want.

  • Resin: a final product printed with this material, when exposed to UV rays, may discolor. Therefore, it is usually painted after printing. Despite this small effect, this material offers precise and smooth prints in addition to the possibility of achieving very desirable textures.

  • Wood: the printing process of this material is very similar to that of ABS and PLA. It is ideal for creating objects that have the same texture, appearance, and smell as wood. However, it is not pure wood. This material is a mixture of recycled wood and binding polymer.

  • HIPS: excellent as a support material and excellent for creating 3D support objects, but the heat can reduce it.

  • Stainless steel: compact printers, desktop, do not usually support this material and is the most complicated to use in prints. It is a combination of wear-resistant stainless steel and copper.

Construction volume / printing area:

This is important because the older you are, the more you can create. It will give you the opportunity to create larger objects. The industrial and specialized ones allow creating objects of up to one cubic meter, while those of desktops that are more compact and generally used by amateurs or amateurs offer the realization of objects of up to 380 cubic millimeters.

Print Speed:

It is affected by the resolution quality, the higher it is, and the faster the print speed will be. As well as the complexity and the material used in the process. Although, in general, small machines range from a speed of 40mm / s to 150mm / s.

Layer Resolution:

An object printed in a low-resolution quality is made up of very thick layers that allow the division between one and the other to be seen. On the contrary, if you choose the high resolution, your final product will be smooth and with very thin layers that will make it less obvious to see the layers that make up the result.

Extrudes:

It is good to consider how many extrudes your 3D printer includes because more than one extrude allows several colors and/or materials to be used at the same time.

Most 3D printers on the market have one nozzle per extrude, but with a double nozzle system, the printing speed can be optimized to more than triple. Recall that the extrude assembly involves a heated print nozzle, it is just the part responsible for the fusion and extrusion of the material.
